600 spf A good general rule of thumb is 20 BTU per square foot. So, a 200 sf room would require a 4000 BTU ac unit. If you use 20btu per square foot to determine the required tonnage, you will be under sizing your system. For example 20btux1500sf=30000btu. There are 12000 btu per ton so you are using a 2.5 ton system to cool 1500 sf.
